1# 2# Bluetooth subsystem configuration 3# 4 5menuconfig BT 6 tristate "Bluetooth subsystem support" 7 depends on NET && !S390 8 depends on RFKILL || !RFKILL 9 help 10 Bluetooth is low-cost, low-power, short-range wireless technology. 11 It was designed as a replacement for cables and other short-range 12 technologies like IrDA. Bluetooth operates in personal area range 13 that typically extends up to 10 meters. More information about 14 Bluetooth can be found at <http://www.bluetooth.com/>. 15 16 Linux Bluetooth subsystem consist of several layers: 17 Bluetooth Core (HCI device and connection manager, scheduler) 18 HCI Device drivers (Interface to the hardware) 19 SCO Module (SCO audio links) 20 L2CAP Module (Logical Link Control and Adaptation Protocol) 21 RFCOMM Module (RFCOMM Protocol) 22 BNEP Module (Bluetooth Network Encapsulation Protocol) 23 CMTP Module (CAPI Message Transport Protocol) 24 HIDP Module (Human Interface Device Protocol) 25 26 Say Y here to compile Bluetooth support into the kernel or say M to 27 compile it as module (bluetooth). 28 29 To use Linux Bluetooth subsystem, you will need several user-space 30 utilities like hciconfig and hcid. These utilities and updates to 31 Bluetooth kernel modules are provided in the BlueZ packages. 32 For more information, see <http://www.bluez.org/>. 33 34config BT_L2CAP 35 tristate "L2CAP protocol support" 36 depends on BT 37 select CRC16 38 help 39 L2CAP (Logical Link Control and Adaptation Protocol) provides 40 connection oriented and connection-less data transport. L2CAP 41 support is required for most Bluetooth applications. 42 43 Say Y here to compile L2CAP support into the kernel or say M to 44 compile it as module (l2cap). 45 46config BT_L2CAP_EXT_FEATURES 47 bool "L2CAP Extended Features support (EXPERIMENTAL)" 48 depends on BT_L2CAP && EXPERIMENTAL 49 help 50 This option enables the L2CAP Extended Features support. These 51 new features include the Enhanced Retransmission and Streaming 52 Modes, the Frame Check Sequence (FCS), and Segmentation and 53 Reassembly (SAR) for L2CAP packets. They are a required for the 54 new Alternate MAC/PHY and the Bluetooth Medical Profile. 55 56 You should say N unless you know what you are doing. Note that 57 this is in an experimental state yet. 58 59config BT_SCO 60 tristate "SCO links support" 61 depends on BT 62 help 63 SCO link provides voice transport over Bluetooth. SCO support is 64 required for voice applications like Headset and Audio. 65 66 Say Y here to compile SCO support into the kernel or say M to 67 compile it as module (sco). 68 69source "net/bluetooth/rfcomm/Kconfig" 70 71source "net/bluetooth/bnep/Kconfig" 72 73source "net/bluetooth/cmtp/Kconfig" 74 75source "net/bluetooth/hidp/Kconfig" 76 77source "drivers/bluetooth/Kconfig" 78 79
